Diode-pumped continuous-wave eye-safe Nd:YAP laser at 1.43μm

Abstract

The continuous-wave (CW) laser properties of an efficient diode-pumped Nd:YAP crystal operating at 1.43 μm formed with a simple plane-concave cavity have been studied. With the incident pump power of 17.8 W, an output power of 2.2 W was obtained, giving an optical conversion efficiency of 12.4% and a slope efficiency of 14.7%. The beam quality factor M 2 was less than 1.2. The power stability was less 2.4% in 60 minutes. Output power at 1.43 μm laser versus the incident pump power

Graphene Q-switched 1.4 µm solid state laser

“…Lasers operating around 1.4 µm can be technically applied in optical communications, LIDAR, and ophthalmology due to its eye-safe property [1][2][3]. Optical parametric oscillators and Raman lasers have been the main equipment used for generating lasers in this spectrum regime for many years [2,4].…”

Diode-end-pumped Nd3+-doped oxyorthosilicate GYSO lasers operating on4F3/2 → 4I13/2transition

“…In one of their important applications, for instance, diode-pumped Nd 3+ -doped lasers have become widely recognized as all-solid-state visible laser sources for nonlinear frequency conversion into blue, green, orange and red [1][2][3][4][5][6]. Compared with conventional Nd 3+ single-crystal laser materials, such as Nd:YAG [7][8][9], Nd:GGG [10,11], Nd:YVO 4 [12,13], Nd:GdVO 4 [14], Nd:YLF [15,16] and Nd:YAP [17,18], in recent years, laser host materials possessing a broad bandwidth have attracted more and more research interest, because these broad bandwidth laser mat erials provide the opportunity to pursue tunable lasers and ultrashort pulse lasers using mode-locking technology. Such a broad bandwidth resulting from inhomogeneous broadening behavior is attributed to multiple substitutional sites with low symmetry, which enhances the structural disorder to a certain extent [19,20].…”
